We're new to Alfresco and Java - and are trying to get an instance of Drupal to speak with our Alfresco installation, housed on Mac OS X. We used the Mac OS X installer - and are using our own MySQL and LDAP connections. We're using the Tomcat that is bundled with Alfresco.
According to what we've read, in order for Drupal [or any outside source] to connect - we need to make sure that IPv4 is being used, by issuing one of the following arguments/commands:
-Djava.net.preferIPv4Stack = true OR java.net.preferIPv4Stack = true
Problem is, we're having a very hard time finding exactly where we should be placing this, particularly not having a lot of experience with Java, and with it hosted on Mac OS X.
